16 Perl::Critic is an extensible framework for creating and applying
17 coding standards to Perl source code. Essentially, it is a static
18 source code analysis engine. Perl::Critic is distributed with a number
19 of Perl::Critic::Policy modules that attempt to enforce various coding
20 guidelines. Most Policy modules are based on Damian Conway's book Perl
21 Best Practices. However, Perl::Critic is not limited to PBP and will
22 even support Policies that contradict Conway. You can enable, disable,
23 and customize those Polices through the Perl::Critic interface. You
24 can also create new Policy modules that suit your own tastes.
25 For a command-line interface to Perl::Critic, see the documentation for
27 perlcritic. If you want to integrate Perl::Critic with your build
28 process, Test::Perl::Critic provides an interface that is suitable for
29 test programs. Also, Test::Perl::Critic::Progressive is useful for
30 gradually applying coding standards to legacy code. For the ultimate
31 convenience (at the expense of some flexibility) see the criticism
32 pragma.
33 If you'd like to try Perl::Critic without installing anything, there is
35 a web-service available at <http://perlcritic.com>. The web-service
36 does not yet support all the configuration features that are available
37 in the native Perl::Critic API, but it should give you a good idea of
38 what it does.
39 Also, ActivePerl includes a very slick graphical interface to Perl-
41 Critic called "perlcritic-gui". You can get a free community edition
42 of ActivePerl from <http://www.activestate.com>.
43
45 This is considered to be a public class. Any changes to its interface
46 will go through a deprecation cycle.

53 => $B, -criticism-fatal => $B)"
54 "new()"
55 Returns a reference to a new Perl::Critic object. Most arguments
56 are just passed directly into Perl::Critic::Config, but I have
57 described them here as well. The default value for all arguments
58 can be defined in your .perlcriticrc file. See the "CONFIGURATION"
59 section for more information about that. All arguments are
60 optional key-value pairs as follows:
61 -profile is a path to a configuration file. If $FILE is not
63 defined, Perl::Critic::Config attempts to find a .perlcriticrc
64 configuration file in the current directory, and then in your home
65 directory. Alternatively, you can set the "PERLCRITIC" environment
66 variable to point to a file in another location. If a
67 configuration file can't be found, or if $FILE is an empty string,
68 then all Policies will be loaded with their default configuration.
69 See "CONFIGURATION" for more information.
70 -severity is the minimum severity level. Only Policy modules that
72 have a severity greater than $N will be applied. Severity values
73 are integers ranging from 1 (least severe violations) to 5 (most
74 severe violations). The default is 5. For a given "-profile",
75 decreasing the "-severity" will usually reveal more Policy
76 violations. You can set the default value for this option in your
77 .perlcriticrc file. Users can redefine the severity level for any
78 Policy in their .perlcriticrc file. See "CONFIGURATION" for more
79 information.
80 If it is difficult for you to remember whether severity "5" is the
82 most or least restrictive level, then you can use one of these
83 named values:
84 SEVERITY NAME ...is equivalent to... SEVERITY NUMBER
86 --------------------------------------------------------
87 -severity => 'gentle' -severity => 5
88 -severity => 'stern' -severity => 4
89 -severity => 'harsh' -severity => 3
90 -severity => 'cruel' -severity => 2
91 -severity => 'brutal' -severity => 1
92 The names reflect how severely the code is criticized: a "gentle"
94 criticism reports only the most severe violations, and so on down
95 to a "brutal" criticism which reports even the most minor
96 violations.
97 -theme is special expression that determines which Policies to
99 apply based on their respective themes. For example, the following
100 would load only Policies that have a 'bugs' AND 'pbp' theme:
101 my $critic = Perl::Critic->new( -theme => 'bugs && pbp' );
103 Unless the "-severity" option is explicitly given, setting "-theme"
105 silently causes the "-severity" to be set to 1. You can set the
106 default value for this option in your .perlcriticrc file. See the
107 "POLICY THEMES" section for more information about themes.
108 -include is a reference to a list of string @PATTERNS. Policy
110 modules that match at least one "m/$PATTERN/ixms" will always be
111 loaded, irrespective of all other settings. For example:
112 my $critic = Perl::Critic->new(-include => ['layout'], -severity => 4);
114 This would cause Perl::Critic to apply all the "CodeLayout::*"
116 Policy modules even though they have a severity level that is less
117 than 4. You can set the default value for this option in your
118 .perlcriticrc file. You can also use "-include" in conjunction
119 with the "-exclude" option. Note that "-exclude" takes precedence
120 over "-include" when a Policy matches both patterns.
121 -exclude is a reference to a list of string @PATTERNS. Policy
123 modules that match at least one "m/$PATTERN/ixms" will not be
124 loaded, irrespective of all other settings. For example:
125 my $critic = Perl::Critic->new(-exclude => ['strict'], -severity => 1);
127 This would cause Perl::Critic to not apply the "RequireUseStrict"
129 and "ProhibitNoStrict" Policy modules even though they have a
130 severity level that is greater than 1. You can set the default
131 value for this option in your .perlcriticrc file. You can also use
132 "-exclude" in conjunction with the "-include" option. Note that
133 "-exclude" takes precedence over "-include" when a Policy matches
134 both patterns.
135 -single-policy is a string "PATTERN". Only one policy that matches
137 "m/$PATTERN/ixms" will be used. Policies that do not match will be
138 excluded. This option has precedence over the "-severity",
139 "-theme", "-include", "-exclude", and "-only" options. You can set
140 the default value for this option in your .perlcriticrc file.
141 -top is the maximum number of Violations to return when ranked by
143 their severity levels. This must be a positive integer.
144 Violations are still returned in the order that they occur within
145 the file. Unless the "-severity" option is explicitly given,
146 setting "-top" silently causes the "-severity" to be set to 1. You
147 can set the default value for this option in your .perlcriticrc
148 file.
149 -only is a boolean value. If set to a true value, Perl::Critic
151 will only choose from Policies that are mentioned in the user's
152 profile. If set to a false value (which is the default), then
153 Perl::Critic chooses from all the Policies that it finds at your
154 site. You can set the default value for this option in your
155 .perlcriticrc file.
156 -profile-strictness is an enumerated value, one of
158 "$PROFILE_STRICTNESS_WARN" in Perl::Critic::Utils::Constants (the
159 default), "$PROFILE_STRICTNESS_FATAL" in
160 Perl::Critic::Utils::Constants, and "$PROFILE_STRICTNESS_QUIET" in
161 Perl::Critic::Utils::Constants. If set to
162 "$PROFILE_STRICTNESS_FATAL" in Perl::Critic::Utils::Constants,
163 Perl::Critic will make certain warnings about problems found in a
164 .perlcriticrc or file specified via the -profile option fatal. For
165 example, Perl::Critic normally only "warn"s about profiles
166 referring to non-existent Policies, but this value makes this
167 situation fatal. Correspondingly, "$PROFILE_STRICTNESS_QUIET" in
168 Perl::Critic::Utils::Constants makes Perl::Critic shut up about
169 these things.
170 -force is a boolean value that controls whether Perl::Critic
172 observes the magical "## no critic" annotations in your code. If
173 set to a true value, Perl::Critic will analyze all code. If set to
174 a false value (which is the default) Perl::Critic will ignore code
175 that is tagged with these annotations. See "BENDING THE RULES" for
176 more information. You can set the default value for this option in
177 your .perlcriticrc file.
178 -verbose can be a positive integer (from 1 to 11), or a literal
180 format specification. See Perl::Critic::Violation for an
181 explanation of format specifications. You can set the default
182 value for this option in your .perlcriticrc file.
183 -unsafe directs Perl::Critic to allow the use of Policies that are
185 marked as "unsafe" by the author. Such policies may compile
186 untrusted code or do other nefarious things.
187 -color and -pager are not used by Perl::Critic but is provided for
189 the benefit of perlcritic.
190 -criticism-fatal is not used by Perl::Critic but is provided for
192 the benefit of criticism.
193 -color-severity-highest, -color-severity-high, -color-severity-
195 medium, -color-severity-low, and -color-severity-lowest are not
196 used by Perl::Critic, but are provided for the benefit of
197 perlcritic. Each is set to the Term::ANSIColor color specification
198 to be used to display violations of the corresponding severity.
199 -files-with-violations and -files-without-violations are not used
201 by Perl::Critic, but are provided for the benefit of perlcritic, to
202 cause only the relevant filenames to be displayed.
203
205 "critique( $source_code )"
206 Runs the $source_code through the Perl::Critic engine using all the
207 Policies that have been loaded into this engine. If $source_code
208 is a scalar reference, then it is treated as a string of actual
209 Perl code. If $source_code is a reference to an instance of
210 PPI::Document, then that instance is used directly. Otherwise, it
211 is treated as a path to a local file containing Perl code. This
212 method returns a list of Perl::Critic::Violation objects for each
213 violation of the loaded Policies. The list is sorted in the order
214 that the Violations appear in the code. If there are no
215 violations, this method returns an empty list.
216 "add_policy( -policy => $policy_name, -params => \%param_hash )"
218 Creates a Policy object and loads it into this Critic. If the
219 object cannot be instantiated, it will throw a fatal exception.
220 Otherwise, it returns a reference to this Critic.
221 -policy is the name of a Perl::Critic::Policy subclass module. The
223 'Perl::Critic::Policy' portion of the name can be omitted for
224 brevity. This argument is required.
225 -params is an optional reference to a hash of Policy parameters.
227 The contents of this hash reference will be passed into to the
228 constructor of the Policy module. See the documentation in the
229 relevant Policy module for a description of the arguments it
230 supports.
231 " policies() "
233 Returns a list containing references to all the Policy objects that
234 have been loaded into this engine. Objects will be in the order
235 that they were loaded.
236 " config() "
238 Returns the Perl::Critic::Config object that was created for or
239 given to this Critic.
240 " statistics() "
242 Returns the Perl::Critic::Statistics object that was created for
243 this Critic. The Statistics object accumulates data for all files
244 that are analyzed by this Critic.
245
247 For those folks who prefer to have a functional interface, The
248 "critique" method can be exported on request and called as a static
249 function. If the first argument is a hashref, its contents are used to
250 construct a new Perl::Critic object internally. The keys of that hash
251 should be the same as those supported by the "Perl::Critic::new()"
252 method. Here are some examples:
253 use Perl::Critic qw(critique);
255 # Use default parameters...
257 @violations = critique( $some_file );
258 # Use custom parameters...
260 @violations = critique( {-severity => 2}, $some_file );
261 # As a one-liner
263 %> perl -MPerl::Critic=critique -e 'print critique(shift)' some_file.pm
264 None of the other object-methods are currently supported as static
266 functions. Sorry.
267
269 Most of the settings for Perl::Critic and each of the Policy modules
270 can be controlled by a configuration file. The default configuration
271 file is called .perlcriticrc. Perl::Critic will look for this file in
272 the current directory first, and then in your home directory.
273 Alternatively, you can set the "PERLCRITIC" environment variable to
274 explicitly point to a different file in another location. If none of
275 these files exist, and the "-profile" option is not given to the
276 constructor, then all the modules that are found in the
277 Perl::Critic::Policy namespace will be loaded with their default
278 configuration.
279 The format of the configuration file is a series of INI-style blocks
281 that contain key-value pairs separated by '='. Comments should start
282 with '#' and can be placed on a separate line or after the name-value
283 pairs if you desire.
284 Default settings for Perl::Critic itself can be set before the first
286 named block. For example, putting any or all of these at the top of
287 your configuration file will set the default value for the
288 corresponding constructor argument.
289 severity = 3 #Integer or named level
291 only = 1 #Zero or One
292 force = 0 #Zero or One
293 verbose = 4 #Integer or format spec
294 top = 50 #A positive integer
295 theme = (pbp || security) && bugs #A theme expression
296 include = NamingConventions ClassHierarchies #Space-delimited list
297 exclude = Variables Modules::RequirePackage #Space-delimited list
298 criticism-fatal = 1 #Zero or One
299 color = 1 #Zero or One
300 allow-unsafe = 1 #Zero or One
301 pager = less #pager to pipe output to
302 The remainder of the configuration file is a series of blocks like
304 this:
305 [Perl::Critic::Policy::Category::PolicyName]
307 severity = 1
308 set_themes = foo bar
309 add_themes = baz
310 maximum_violations_per_document = 57
311 arg1 = value1
312 arg2 = value2
313 "Perl::Critic::Policy::Category::PolicyName" is the full name of a
315 module that implements the policy. The Policy modules distributed with
316 Perl::Critic have been grouped into categories according to the table
317 of contents in Damian Conway's book Perl Best Practices. For brevity,
318 you can omit the 'Perl::Critic::Policy' part of the module name.
319 "severity" is the level of importance you wish to assign to the Policy.
321 All Policy modules are defined with a default severity value ranging
322 from 1 (least severe) to 5 (most severe). However, you may disagree
323 with the default severity and choose to give it a higher or lower
324 severity, based on your own coding philosophy. You can set the
325 "severity" to an integer from 1 to 5, or use one of the equivalent
326 names:
327 SEVERITY NAME ...is equivalent to... SEVERITY NUMBER
329 ----------------------------------------------------
330 gentle 5
331 stern 4
332 harsh 3
333 cruel 2
334 brutal 1
335 The names reflect how severely the code is criticized: a "gentle"
337 criticism reports only the most severe violations, and so on down to a
338 "brutal" criticism which reports even the most minor violations.
339 "set_themes" sets the theme for the Policy and overrides its default
341 theme. The argument is a string of one or more whitespace-delimited
342 alphanumeric words. Themes are case-insensitive. See "POLICY THEMES"
343 for more information.
344 "add_themes" appends to the default themes for this Policy. The
346 argument is a string of one or more whitespace-delimited words. Themes
347 are case- insensitive. See "POLICY THEMES" for more information.
348 "maximum_violations_per_document" limits the number of Violations the
350 Policy will return for a given document. Some Policies have a default
351 limit; see the documentation for the individual Policies to see whether
352 there is one. To force a Policy to not have a limit, specify
353 "no_limit" or the empty string for the value of this parameter.
354 The remaining key-value pairs are configuration parameters that will be
356 passed into the constructor for that Policy. The constructors for most
357 Policy objects do not support arguments, and those that do should have
358 reasonable defaults. See the documentation on the appropriate Policy
359 module for more details.
360 Instead of redefining the severity for a given Policy, you can
362 completely disable a Policy by prepending a '-' to the name of the
363 module in your configuration file. In this manner, the Policy will
364 never be loaded, regardless of the "-severity" given to the
365 Perl::Critic constructor.
366 A simple configuration might look like this:
368 #--------------------------------------------------------------
370 # I think these are really important, so always load them
371 [TestingAndDebugging::RequireUseStrict]
373 severity = 5
374 [TestingAndDebugging::RequireUseWarnings]
376 severity = 5
377 #--------------------------------------------------------------
379 # I think these are less important, so only load when asked
380 [Variables::ProhibitPackageVars]
382 severity = 2
383 [ControlStructures::ProhibitPostfixControls]
385 allow = if unless # My custom configuration
386 severity = cruel # Same as "severity = 2"
387 #--------------------------------------------------------------
389 # Give these policies a custom theme. I can activate just
390 # these policies by saying `perlcritic -theme larry`
391 [Modules::RequireFilenameMatchesPackage]
393 add_themes = larry
394 [TestingAndDebugging::RequireTestLables]
396 add_themes = larry curly moe
397 #--------------------------------------------------------------
399 # I do not agree with these at all, so never load them
400 [-NamingConventions::Capitalization]
402 [-ValuesAndExpressions::ProhibitMagicNumbers]
403 #--------------------------------------------------------------
405 # For all other Policies, I accept the default severity,
406 # so no additional configuration is required for them.
407 For additional configuration examples, see the perlcriticrc file that
409 is included in this examples directory of this distribution.
410 Damian Conway's own Perl::Critic configuration is also included in this
412 distribution as examples/perlcriticrc-conway.
413
415 A large number of Policy modules are distributed with Perl::Critic.
416 They are described briefly in the companion document
417 Perl::Critic::PolicySummary and in more detail in the individual
418 modules themselves. Say "perlcritic -doc PATTERN" to see the perldoc
419 for all Policy modules that match the regex "m/PATTERN/ixms"
420 There are a number of distributions of additional policies on CPAN. If
422 Perl::Critic doesn't contain a policy that you want, some one may have
423 already written it. See the "SEE ALSO" section below for a list of
424 some of these distributions.
425
427 Each Policy is defined with one or more "themes". Themes can be used
428 to create arbitrary groups of Policies. They are intended to provide
429 an alternative mechanism for selecting your preferred set of Policies.
430 For example, you may wish disable a certain subset of Policies when
431 analyzing test programs. Conversely, you may wish to enable only a
432 specific subset of Policies when analyzing modules.
433 The Policies that ship with Perl::Critic have been broken into the
435 following themes. This is just our attempt to provide some basic
436 logical groupings. You are free to invent new themes that suit your
437 needs.
438 THEME DESCRIPTION
440 --------------------------------------------------------------------------
441 core All policies that ship with Perl::Critic
442 pbp Policies that come directly from "Perl Best Practices"
443 bugs Policies that that prevent or reveal bugs
444 certrec Policies that CERT recommends
445 certrule Policies that CERT considers rules
446 maintenance Policies that affect the long-term health of the code
447 cosmetic Policies that only have a superficial effect
448 complexity Policies that specifically relate to code complexity
449 security Policies that relate to security issues
450 tests Policies that are specific to test programs
451 Any Policy may fit into multiple themes. Say "perlcritic -list" to get
453 a listing of all available Policies and the themes that are associated
454 with each one. You can also change the theme for any Policy in your
455 .perlcriticrc file. See the "CONFIGURATION" section for more
456 information about that.
457 Using the "-theme" option, you can create an arbitrarily complex rule
459 that determines which Policies will be loaded. Precedence is the same
460 as regular Perl code, and you can use parentheses to enforce precedence
461 as well. Supported operators are:
462 Operator Alternative Example
464 -----------------------------------------------------------------
465 && and 'pbp && core'
466 || or 'pbp || (bugs && security)'
467 ! not 'pbp && ! (portability || complexity)'
468 Theme names are case-insensitive. If the "-theme" is set to an empty
470 string, then it evaluates as true all Policies.
471
473 Perl::Critic takes a hard-line approach to your code: either you comply
474 or you don't. In the real world, it is not always practical (nor even
475 possible) to fully comply with coding standards. In such cases, it is
476 wise to show that you are knowingly violating the standards and that
477 you have a Damn Good Reason (DGR) for doing so.
478 To help with those situations, you can direct Perl::Critic to ignore
480 certain lines or blocks of code by using annotations:
481 require 'LegacyLibaray1.pl'; ## no critic
483 require 'LegacyLibrary2.pl'; ## no critic
484 for my $element (@list) {
486 ## no critic
488 $foo = ""; #Violates 'ProhibitEmptyQuotes'
490 $barf = bar() if $foo; #Violates 'ProhibitPostfixControls'
491 #Some more evil code...
492 ## use critic
494 #Some good code...
496 do_something($_);
497 }
498 The "## no critic" annotations direct Perl::Critic to ignore the
500 remaining lines of code until a "## use critic" annotation is found. If
501 the "## no critic" annotation is on the same line as a code statement,
502 then only that line of code is overlooked. To direct perlcritic to
503 ignore the "## no critic" annotations, use the "--force" option.
504 A bare "## no critic" annotation disables all the active Policies. If
506 you wish to disable only specific Policies, add a list of Policy names
507 as arguments, just as you would for the "no strict" or "no warnings"
508 pragmas. For example, this would disable the "ProhibitEmptyQuotes" and
509 "ProhibitPostfixControls" policies until the end of the block or until
510 the next "## use critic" annotation (whichever comes first):
511 ## no critic (EmptyQuotes, PostfixControls)
513 # Now exempt from ValuesAndExpressions::ProhibitEmptyQuotes
515 $foo = "";
516 # Now exempt ControlStructures::ProhibitPostfixControls
518 $barf = bar() if $foo;
519 # Still subjected to ValuesAndExpression::RequireNumberSeparators
521 $long_int = 10000000000;
522 Since the Policy names are matched against the "## no critic" arguments
524 as regular expressions, you can abbreviate the Policy names or disable
525 an entire family of Policies in one shot like this:
526 ## no critic (NamingConventions)
528 # Now exempt from NamingConventions::Capitalization
530 my $camelHumpVar = 'foo';
531 # Now exempt from NamingConventions::Capitalization
533 sub camelHumpSub {}
534 The argument list must be enclosed in parentheses or brackets and must
536 contain one or more comma-separated barewords (e.g. don't use quotes).
537 The "## no critic" annotations can be nested, and Policies named by an
538 inner annotation will be disabled along with those already disabled an
539 outer annotation.
540 Some Policies like "Subroutines::ProhibitExcessComplexity" apply to an
542 entire block of code. In those cases, the "## no critic" annotation
543 must appear on the line where the violation is reported. For example:
544 sub complicated_function { ## no critic (ProhibitExcessComplexity)
546 # Your code here...
547 }
548 Policies such as "Documentation::RequirePodSections" apply to the
550 entire document, in which case violations are reported at line 1.
551 Use this feature wisely. "## no critic" annotations should be used in
553 the smallest possible scope, or only on individual lines of code. And
554 you should always be as specific as possible about which Policies you
555 want to disable (i.e. never use a bare "## no critic"). If
556 Perl::Critic complains about your code, try and find a compliant
557 solution before resorting to this feature.
558
560 Coding standards are deeply personal and highly subjective. The goal
561 of Perl::Critic is to help you write code that conforms with a set of
562 best practices. Our primary goal is not to dictate what those
563 practices are, but rather, to implement the practices discovered by
564 others. Ultimately, you make the rules -- Perl::Critic is merely a
565 tool for encouraging consistency. If there is a policy that you think
566 is important or that we have overlooked, we would be very grateful for
567 contributions, or you can simply load your own private set of policies
568 into Perl::Critic.
569
571 The modular design of Perl::Critic is intended to facilitate the
572 addition of new Policies. You'll need to have some understanding of
573 PPI, but most Policy modules are pretty straightforward and only
574 require about 20 lines of code. Please see the Perl::Critic::DEVELOPER
575 file included in this distribution for a step-by-step demonstration of
576 how to create new Policy modules.
577 If you develop any new Policy modules, feel free to send them to
579 "<team@perlcritic.com>" and I'll be happy to consider putting them into
580 the Perl::Critic distribution. Or if you would like to work on the
581 Perl::Critic project directly, you can fork our repository at
582 <https://github.com/Perl-Critic/Perl-Critic.git>.
583 The Perl::Critic team is also available for hire. If your organization
585 has its own coding standards, we can create custom Policies to enforce
586 your local guidelines. Or if your code base is prone to a particular
587 defect pattern, we can design Policies that will help you catch those
588 costly defects before they go into production. To discuss your needs
589 with the Perl::Critic team, just contact "<team@perlcritic.com>".

677 Scrutinizing Perl code is hard for humans, let alone machines. If you
678 find any bugs, particularly false-positives or false-negatives from a
679 Perl::Critic::Policy, please submit them at
680 <https://github.com/Perl-Critic/Perl-Critic/issues>. Thanks.
